Working with Kanzi Monitor services

Kanzi Monitor provides several services that you can use to profile, debug, and inspect your Kanzi application at runtime. Each service addresses a specific diagnostic task and can be enabled or disabled independently in the Kanzi Monitor configuration file.

Profiling Trace Service

Collects runtime profiling data from the Kanzi Engine and writes it to a JSON trace file compatible with the Perfetto trace viewer. Use this service to analyze frame timing, rendering stages, and engine operations.

See Using the Profiling Trace service

Command Processor Service

Provides a command-line interface for interacting with the Kanzi Engine at runtime. You can send commands through a local terminal, a remote TCP connection, or a serial port (UART).

See Using the Command Processor service

UI Service

Renders graphical overlays on top of the regular Kanzi application content to display runtime information and help identify rendering issues. Other services, such as the Log service, can also register their own overlay screens.

See Using the UI service

Log Service

Captures Kanzi Engine log messages into an in-memory ring buffer. You can view log entries through the console, on-screen overlay, or as part of a profiling trace.

See Using the Log service

Performance Service

Continuously measures runtime performance metrics such as frame rate, frame timing, and rendering statistics. These metrics are exported as counter tracks in the Perfetto trace viewer.

See Using the Performance service

Overwatch Service

Provides JSON-based remote introspection of a running Kanzi application. Exposes the scene graph, node properties, resources, textures, performance metrics, and more through a set of overwatch.* commands.

See Using the Overwatch service

Monitor Web UI

A browser-based graphical interface for remotely inspecting and debugging Kanzi applications. Connects to the Overwatch service through a Python WebSocket bridge and provides visual tools for browsing the scene graph, editing properties, previewing textures, and capturing traces.

See Using the Monitor Web UI

MCP Server

A Python tool that exposes all Overwatch commands as structured tools for AI assistants such as Claude Code and Claude Desktop. Connects over TCP or serial and enables AI agents to inspect and control a running Kanzi application through the Model Context Protocol.
